"If I could do minus on the stars I would give a -5 stars. This company is horrible and Skylar Jump is rude beyond beleif. He came out and did the bid for the job, and he told me what it would cost me. 1/2 down and the other 1/2 upon completion of the job. They installed new drywall but did not make it flush at the corners, leaving big gaps and putting in large gouges. He and his crew left garbage all over the yard, stole materials and left my house compromised and exposed to the elements. Also damaged some of my vintage furniture from the Hoquiam Castle. So no replacing those. He was calling me and his crew inappropriate names and telling me that I don't listen, constantly interrupting me and told me that my family member who is an expert in siding doesn't know anything and started dising people. Also will not give you a receipt for money paid and will not give you a break down of the job. Also, when picking up materials from Home Depot, he will charge materials for another job onto your account. Do not hire this company unless you want to punish yourself and lose your money."

Standing water in your crawl space won’t disappear on its own. Keep the drainage clear, ensure the vents are working properly, and run a dehumidifier to control moisture levels. If dampness lingers, mold, wood rot, and foundation cracks can follow. Act quickly and call a pro to protect your home’s structure and indoor air quality.
Disinfecting a crawl space requires a methodical approach. First, clear all debris and remove old liners and insulation to eliminate contaminants. Then, apply a strong bleach solution or borate spray to eradicate mold spores and mildew. Ensuring complete surface coverage and allowing ample drying time establishes a sanitary environment and prevents future infestations.
A crawl space serves vital functions by providing access to essential systems, including electrical wiring, plumbing, and HVAC ducts. It also offers a buffer zone that aids in moisture control and protects underlying structural components.
Yes, crawl space encapsulation is a worthwhile investment in protecting your home. Crawl space encapsulation locks out moisture, controls humidity, and blocks pests and harmful pollutants like radon gas. Those benefits boost indoor air quality and protect beams, joists, and insulation, giving your home long‑term structural stability and safeguarding your family’s health.
Prevention is the best way to keep water out of your crawl space. A dehumidifier and sump pump can help control moisture levels, but grading the landscape to redirect water away from the foundation is most important. Additionally, seal foundation cracks and install reliable drainage systems such as a French drain to maintain a consistently dry environment.
Yes, repairing your crawl space foundation is critical, regardless of how minor the issue may seem. Foundation problems arise from enduring moisture, water intrusion, and unstable soil, which can lead to significant structural damage if left unaddressed. Hiring a licensed structural engineer or foundation repair professional guarantees your home’s long-term stability and safety while preventing escalating repair costs.
